The individual bytes in this
multibyte register can be accessed with the following register names:
NCOxACCU: Accesses the
upper byte ACC[23:16]
NCOxACCH: Accesses the
high byte ACC[15:8]
NCOxACCL: Accesses the
low byte ACC[7:0].
The accumulator spans registers
NCOxACCU:NCOxACCH:NCOxACCL. The 24 bits are reserved, but not all are used.
This register updates in real-time, asynchronously to the CPU; there is no
provision to ensure atomic access to this 24-bit space using an 8-bit bus.
Writing to this register while the module is operating will produce undefined
results.
